CICHLOSOMA.— PETENIA. 29 



From Dr. Meek's* description of adult specimens of his C. mojarra, founded on a 

 small example with malformed spinous dorsal, it is evident that this species is identical 

 with G. trimaculatum, and not with the closely allied C. salvini, as I at first supposed.

The single species is allied to Cichlosoma dovii and C. managuense, but has the 

 mouth larger and the maxillary more exposed, whilst the praemaxillary processes are 

 as long as the head and extend nearly to the origin of the dorsal fin.
